BME680 Temperature Humidity Pressure and Gas Sensor
Now available from PMD Way is this incredibly multi-talented BME680 Temperature Humidity Pressure and Gas Sensor board.
The BME680 can measure humidity with +/-3% accuracy, barometric pressure with +/-1 hPa absolute accuracy, and temperature with +/-1.0°C accuracy. As pressure changes with altitude, the sensor can also be used as an altimeter with +/-1 metre or better accuracy.
Along with the other readings, the BME680 has a small metal-oxide sensor. This changes resistance based on the volatile organic compounds in the air, and thus can be used to detect gases and alcohols such as Ethanol, Alcohol and Carbon Monoxide to perform air quality measurements. Note it will give you one resistance value, with overall VOC content, but it cannot differentiate gasses or alcohols.
It is recommended to run the sensor board for 48 hours before initial use, and then run the sensor for 30 minutes in the required mode every time the sensor is used. See datasheet (link below) for more information.
Board can be used with both 5V and 3.3V.
